Abstract

Graphene is used in a variety of chemical, thermal, mechanical, and electrical applications. It contains one carbon atomic slide. This paper proposes a graphene-based plasmonic antenna array for THz applications. Additionally, the THz SPP waves (Surface Plasmon Polariton) phenomenon in graphene is shown. The proposed antenna is made up of four by six graphene patches, which are excited by a graphene Nano ribbon feeder placed on top of an alumina layer. CST 2020 software was used to simulate and study the antenna. As per the findings, the antenna operates in the frequency ranges [(2.6-10), (2.28-2.5), (1.87-2.14), and (1.4-1.6) ] THz, where S11 is equal to or less than -10 dB. The antenna's gain is high in these frequency band regions.
